Istio Rate Limiting not working on apps other than bookinfo

Hi I’m applying Rate Limiting on istio 1.1.6 using the official documentation link

Rate limiting works on the bookinfo sample application as shown in the documentation link. But when I try it on some other app it doesn’t work. I have tried a lot but no luck.

Can someone please guide me in this regard.

The goal I am trying to achieve is to apply a default rate limit on all the kubernetes services.

Any reason you are using Istio 1.1.6? It’s out of support. afaik…
